| 摘 要： | 通过野外实地调研,在详细研究金堆城露天矿排土场高边坡地质条件和边坡变形破坏特征的基础上,分析了该边坡的变形破坏机制,将破坏方式归纳为两种类型:蠕滑-拉裂破坏,拉裂-滑移破坏。通过圆弧法和破坏概率法计算和分析了高边坡在天然、爆破振动和地震条件下5个不同剖面地段的稳定性状态,并利用FLAC数值模拟进行验证,最后,根据变形破坏方式提出了相应的处理措施。为高边坡的稳定性评价、预测和防治提供了有价值的参考。 |

| Abstract: | According to on-site field investigation,a detailed study of the geological conditions and the characteristic of deformation and failure of the high slope are carried out at dumping site of Jinduicheng open pit mine.The mechanism of deformation and failure of the high slope is concluded to two types,that is creep-cracking and cracksliding.The stabilities of the high slope at five different profiles are calculated and analyzed by using the arc method and the failure probability method on conditions of natural state,blasting and earthquake.FLAC is also used to evaluate the stability of the high slope.This paper provides valuable references in evaluating,forecasting and preventing the landslide. |
